Performance detection method

Abstract

Proposed is a performance detection method for use in detection of performance characteristics of air conditioning equipment. The method includes, for the standard operational status for the air conditioning equipment, capturing a plurality of standard operational parameters to generate performance models; and, during the actual operational status, capturing a plurality of actual operational parameters for conducting analysis based on performance models so as to determine the performance characteristics of the air conditioning equipment and send out a warning when the performance characteristics of the air conditioning equipment are determined to be abnormal. The invention improves on the detection accuracy of prior techniques and enables effective control of air conditioning equipment that eventually saves electrical power and costs as a result.
